Re: mounts too slow(?) causes apps to create dirs in mount p

I'm aware of sleep, thanks.

I don't really see an elegant way to use it however, since these are services that are automatically starting, and adding in a random delay for every start (on bootup or not) seems silly..

Re: mounts too slow(?) causes apps to create dirs in mount p

I guess I should clarify a bit - I think what happens is, the processes look for the drive directory structure, don't see it, and create their own directory structure. Then when the mount happens automatically, it's fails, because the mount point isn't empty. Either way I'm not sure how to fix this ...

USB mounts too slow(?) pi2 [SOLVED]

Hey guys I have an external HD hooked up to my pi, and it mounts fine with sudo mount -a. But when I reboot the pi, I have some processes that start and if they don't find the directory structure they are looking for, they start making their own. So somehow, I end up with my HD not mounted, and blan...

Re: Kernel panic VFS unable to mount unknown block

Well, I managed to fix it, but I didn't really know what I was doing. (From a second SD card with a valid OS) sudo fdisk -l DID show me my partition, yay. Also (from a guide, but I can't find the link now unfortunately) sudo fsck.ext4 -v /dev/sdaX sudo mke2fs -n /dev/sdaX sudo e2fsck -b (first super...

Kernel panic VFS unable to mount unknown block

Hi guys I have a pi that has failed to boot suddenly. I have a butt load of stuff that won't be easy to recreate on it, and so far, I haven't been able to recover. When I put the sdcard in a USB reader and attach it to a 2nd pi, I get this: /dev/mmcblk0p1: SEC_TYPE="msdos" LABEL="boot" UUID="15CD-3B...

A RPI2 NAS with SATA?

Hi All Has anyone built a JBOD NAS with an RPI2 for internal SATA drives? I have a lot of drives packed into machines that I wouldn't mind centralizing in a low power setup. I don't need a lot of performance, a USB gigabit LAN would be OK. The real question in my mind is - how to power, house, and c...

Re: Rasbiam ARMv7 optimization

Be aware that the biggest performance drag is a slow sd card. A slow sd can be class 10, 20mb/s, but it's the UNPUBLISHED stat of random queued writes that makes the difference.

This made my life very unpleasant for quite some time.

There's a thread somewhere here on this forum with some benchmarks, I'm on my mobile so I can't look it up for you. Both of the better performing sds were uhs-1 rated but I think Samsung sds were rated pretty highly in that thread.

But, I haven't fully got it to automatically launch or work all the time so thats as much as I can point you in the right direction.
